I think homicide will be far more popular than suicide. Even given the motivation and means, suicide is still an intrinsically self-limiting proposition, and one that goes against natural selection. Homicide, if sufficiently selective, could improve Darwinian success and offers massive scaling opportunities.

This comment is intended to be darkly tongue in cheek, but I do think homicide is a better fit with human nature.
